INTRODUCTION This service manual was prepared for use by Authorized Warranty Stations and contains service information for Marantz Model 112 Stereophonic Tuner. Servicing information and voltage data included in this manual are intended for use by the knowledgeable and experienced technician only. All instructions should be read carefully. No attempt should be made to proceed without a good understanding of the operation of the tuner. The parts list furnishes information by which replacement parts may be ordered from the Marantz Company. A belief description is included for parts which can be usually be obtained through local suppliers. 2. AM TUNER The AM Tuner section of the Model 112 is contained in the AM/F circuit package consisting of one IC H202 (AN217) and three transistors. The IC is shown in Figure 1 in the block diagram form. The respective three transistors serve as RF amplifier, IF amplifier for intensifying the gain of the IC, and audio amplifier for magnifying the detected audio signal. FM IF FM IF AMPLIFIER(1) AMPLIFIER(2) AM MIXER AM IF OSCILLATOR AMPLIFIER Figure 1. Block Diagram of the AN217 The IC includes an FM IF section and AM Tuner section, each of which comprises two functional blocks. The first block of the FM IF section is an FM IF amplifier (1), the input of which is fed from pin 0, and the output is led to pin . The second block is an FM IF amplifier (2), the input of which is fed from pin 5 and the output is led to pin 8. The first block of the AM Tuner, on the other hand, is an AM mixer and oscillator, the input of which is fed from pin 3 and the output is led to pin 12 . The second block is an AM IF amplifier, the input of which is fed from pin 0 and the output is led to the pin .. All components except the tuning capacitor and ferrite bar antenna are mounted on the printed circuit board P200. An AM signal induced in the ferrite bar antenna is led to the base of the RF amplifier transistor (H209) and amplified to a level required for overcoming the conversion noises, thus giving good S/N performance. The tuned circuit inserted in each of the output and input circuits of the RF amplifier assures very high image and spurious rejection performance. Then, the amplified and selected AM signal is fed to one input (pin 13 ) of the Mixer section of the ICIH202) (pin ® ). While the local oscillator voltage is injected to the other input (pin (4) of the section through the capacitor C244. Then, both AM signal and local oscillator signal are mixed and converted into 455kHz intermediate-frequency signal. The resulting IF signal is led to the first IF transformer L205 consisting of one ceramic filter and two tuned circuits. ... . .: :::.:. The output of L205 is led to the additional IF amplifier (H210) for intensifying the AM IF gain. The output, in turn, is led through the coupling capacitor C253 to the input (pin ) of the AM IF section in the IC(H202), where the output is amplifed to a sufficient level to drive the detector. The fully amplified IF output derived from pin 9 is applied to the diode H228 to detect audible signal through the detector transformer L206. The detected audio signal is filtered and amplified, and the final audio output is obtained from the collector of H211 and applied to the output jacks through the function switch. The DC component of the detected IF signal is used as an AGC voltage to control the emitter current of the IF amplifier H210 through the resistor R273 and R271, and then, the emitter voltage derived from transistor H210 controls the collector voltage of the RF amplifier H209. A part of the 1F signal output is also applied to the diode H229 through the capacitor C257 and is rectified to obtain DC current for energizing the AM signal strength meter M001. 2.1 Suggestions for Troubleshooting AM Tuner Check for broken AM bar antenna, next try to tune a station by rotating the fly-wheel tuning knob slowly and observe the AM signal strength meter whether it deflects or not. If the signal strength meter gives a deflection at several frequencies received, no failure may exist in the stages at least preceding final 1F transformer L206. Mext connect an oscilloscope to the test point A or J218 and check for audio signals with the tuning meter deflected. If the signal strength meter does not deflect, check the local oscillator circuit. Normal oscillating voltage at the hot end of the oscillator tuning capacitor is about 1.5 or 3 volts, varying with tuning capacitor position. When measuring the oscillating voltage use an RF VTVM, no circuit tester gives correct indication. If the local oscillator voltage is normal, check all voltage distribution in the AM circuits by using a DC VTVM and compare the measured values with those given in the schematic diagram. 3. FM TUNER The FM tuner section of the Model 112 consists of four functional blocks: FM Front End, IF Amplifier & Detector, Muting Control and MPX Stereo Decoding Circuit. An FM signal induced by the FM antenna is led to the FM antenna coil L101 through the balun coil. The signal is then fed to the FET RF amplifier, which in turn feed its output to the next Mixer H102 through the double-tuned high-selective circuit. The Mixer converts its input signal into 10.7MHz intermediate-frequency signal and amplifies it at the same time. The H103 is a local oscillator and its output is injected into the base of the Mixer, the injection voltage is about 60mV. The 10.7MHz front end output is led to the next IF amplifier portion through the coaxial cable. The 1F section consists of five IF amplifer stages and one sub IF amplifier stage. The second and third stages of the five-stage IF amplifier, contained in the IC H202, serve as limiter. Three pieces of dual element ceramic filters are also used to obtain high selectivity, two IC limiter stages (H202) and a symmetrical diode limiter are also employed for the best limiting characteristics, improved capture ratio and good AM suppression. A part of the 1F amplifier H201 output is rectified by the diodes H220 and H221 and its DC output is fed back to the gate of the FET RF amplifier to decrease the gain with increase of the signal strength. The IF signal sufficiently amplified through every IF amplifier stage is finally fed to the detector amplifier. The detected audio output is led to: (a) the Quadradial Jack on the rear panel through the resistor R233 and (b) the MPX stereo decoding IC H215 through R289 and H212. 3.1 Audio Muting and Stereo Mode Auto-Selecting Circuit The muting circuit consisting of all solid-state electrical switching is incorporated in the Model 112. 2 . . 1. . . ' S . si. Who he wasiwa The DC voltage obtained by rectifing the sub IF output signal from the H205 is applied to the base of H206 and turns on it, if the sub IF output is greater than predetermined level (muting threshold level). When the H206 is turned on, the H207 is turned off, allowing the emitter-collector resistance to be increased and the collector voltage to be raised to about 9V. The raised collector voltage increases the gate bias voltage and turns on the switching FET H212, decreasing the sourcedrain resistance to near zero ohm and allowing the audio signal applied to the source to flow to the decoding IC pin through the source-drain path. When the input signal is lower than predetermined level, the DC output obtained is small and can not turn on the H206, thus H206 keeps its turn-off state. This makes H207 turn on, decreasing the collector voltage and turning H212 off. Thus no audio signals can pass through the FET. The transistor H208 also turns off when the transistor H207 turns on, and makes the transistor H213 turn on, which is connected to pin 8 on the MPX decoding IC. Therefore, pin ® is equivalently grounded, and the operation of the IC becomes monaural. This prevents misoperation of stereo due to undesirable noises during deviation of tuning. 3.2 MPX Stereo Decoding Circuit The stereo composite signal from the FM Detector undergoes phase compensation by R289 amd C255, is led through the muting switching FET H212 to the input terminal pin 2 of the MPX stereo decoding IC H215 on PLL (Phase Locked Loop) basis, and is decoded into the left and right stereo signals, which become available at pins 4 and 6 respectively. These decoded left and right stereo audio signals are introduced through the low pass filter consisting of L207 to L210 and C273 to C282 for elimination of undesirable residual switching signal and through the de-emphasis network consisting of R308, R309, C283 and C284, into the non-pnp direct coupled audio amplifier, where the signals are amplified to a required level for the output from J226 and J227. From these jacks, the audio signals are led through the function switch and FM Dolby level preset resistors RS03 and RS04 to the output terminals on the rear panel. Figure 2 presents an internal block diagram showing the functions of the PLL basis MPX stereo decoding IC HA1156.

Block Diagram of the HA1156 . . . i ar The input stereo composite signal, amplified by the audio amplifier, is delivered to the phase detectors PD-1 and PD-2. A part of the stereo composite signal is also delivered to the stereo decoder section. The VCO (Voltage Control Oscillator) produces a free run oscillation in the neighborhood of 76kHz with the time constant determined by the capacitor C305 and resistors R311 and R312 set on the outside of pin . The VCO output has its frequency divided into 19kHz through the two frequency divider stages (DIV-1, DIV-2), and is reverted to the phase detector PD-1, which contains two input terminals designed to produce an output in proportion to the product of the two input signals. The signal led to PD-1 input one is a 19kHz square wave formed through frequency division of the 76kHz VCO output signal by the two frequency divider stages DIV-1 and DIV-2, and the 19kHz pilot signal included in the stereo composite signal as a reference signal is led to the other PD-1 input. Therefore, the output of the PD-1 which has passed through the low pass filter LPF-1 provides DC output voltage in proportion to the phase variance between the two inputs. This DC output voltage is amplified by the DC amplifier, and supplied to the 76k Hz VCO as a control voltage. This means that the output frequency and phase of the VCO have been phase-locked to the input pilot signal. The 38k Hz sub-carrier reproduced by the PLL as stated above is delivered through the stereo switch to the stereo decoder section as a switching signal, thus driving the decoder stage. One PD-2 input is given the 19kHz resulting from the frequency division completed by the DIV-1 and DIV-3, whereas the other input gets the 19kHz output contained in the composite signal, and the output is provided with a DC output in proportion to the amplitude of the pilot signal. This DC output is furnished through the LPF-2 to the trigger amplifier which drives the stereo indicator lamp and stereo switch. Therefore, insufficient supply of the pilot signal results in failure to light the stereo indicator and to turn on the stereo switch located in the path of the 38k Hz switching signal, thereby avoiding a wrong stereo operation. H213 attached on the outside of pin ® is a switching transistor for automatic monaural-stereo switchover. When the intensity of an incoming signal from an FM station is weaker than a predetermined level, this H213 is turned on and pin 8 is grounded, thereby developing a condition for monaural reception. For a .forced monaural operation, switch the MODE switch to "MONO", and H213 comes into an “On" condition with the positive bias voltage applied to the base, and pin 8 is grounded, thereby establishing monaural operation. The transistor H214 connected externally to pin 14 is intended to stop the 76kHz oscillation of the VCO which interferes an AM signal during the reception of an AM station. When the function switch is set to "AM" position, a positive bias is charged on the base of H214, H214 is turned on, and pin 14 is grounded. Thus, the oscillation of the VCO is stopped, ending the interference with AM reception. 3.3 Suggestion for Troubleshooting FM Tuner 3.3.1 Symptom: No FM Reception First, turn on the Power switch and try to tune FM stations. Rotate the fly-wheel tuning knob slowly and observe the FM tuning meter. If the tuning meter deflect at several received frequencies, the tuner circuits preceding the discriminator circuit may have no failure. When no reading is obtained in the meter, check the FM local oscillator circuit, using an RF VTVM. The normal local oscillator voltage is one or two volts (rms) at the tuning capacitor, depending on the tuning capacitor position. If the local oscillator voltage is normal, then check all voltage distribution in the FM Front End and IF amplifier unit and compare them with those shown in the circuit diagram. When the tuning meter deflects but no sound is obtained, check the audio circuit, using a high sensitive oscilloscope. 3.3.2 Symptom: No Stereo Separation First, check that the "MONO" swith is in normal out position. Connect an FM RF signal generator output modulated by a stereo modulator to the rear FM antenna terminals, and check whether the stereo beacon is turned on or not. If not turned on, check for 19K Hz VCO output signal (test point®, R304), using an oscilloscope and frequency counter. .. . 1 4.
